Cats typically "scream" or make loud, high-pitched meows when they are in distress, such as being trapped or injured. This behavior is often accompanied by a tense body posture and dilated pupils.

A cat's scream, often referred to as a "caterwaul," is a distinctive and complex vocalization that serves various purposes in feline communication. To understand how a cat screams, one must delve into the anatomy of its vocal apparatus and the physiological processes involved in producing this sound.
Cats possess a highly specialized larynx, or voice box, which is responsible for generating their unique vocal repertoire. The larynx contains two vocal cords, or folds, that vibrate when air passes over them. In cats, these folds are particularly flexible and can be adjusted to produce a wide range of sounds, including meows, purrs, hisses, and screams.
When a cat screams, it employs a specific set of muscles in the larynx and throat to alter the shape and tension of the vocal cords. This process is known as phonation, and it allows cats to modulate the pitch, volume, and timbre of their screams. The laryngeal muscles contract rapidly, causing the vocal cords to stretch and thin out, which in turn increases the frequency at which they vibrate. This high-frequency vibration produces the characteristic high-pitched sound of a cat's scream.
In addition to the larynx, the respiratory system also plays a crucial role in generating a cat's scream. As air is expelled from the lungs through the trachea and into the larynx, it passes over the vibrating vocal cords, amplifying the sound produced by their movement. The force and speed at which air is exhaled can be controlled by the muscles of the diaphragm and abdomen, allowing cats to vary the intensity and duration of their screams.
The acoustic properties of a cat's scream are further influenced by the shape and size of its vocal tract, which includes the pharynx, mouth, and nasal passages. The resonant frequencies of these structures can enhance or suppress certain frequencies within the scream, contributing to its overall timbre and perceived quality.
Cats typically employ their screams in situations where they feel threatened, frightened, or in pain. This vocalization serves as a powerful means of communicating distress or aggression, both to other cats and to humans. By understanding the physiological mechanisms behind a cat's scream, one can gain insights into the intricate world of feline communication and better appreciate the richness of their vocal repertoire.
